Mutt 1.3.xx and charset

[Heinz Diehl]

Hi!

I just switched from Mutt-1.2.5i to 1.3.14i, and the first thing I
noticed is that German umlauts are replaced by a "?" in all mails which
contain a "Content-Type: text/plain;" header. Mutt-1.2.5 displayed them
properly as it should be, and reading the docs and changes didn't lead me
further. 
Locale is set-up and works properly, so this can't be the cause.
Does anybody have a small hint for me?
